This caught me a little off-guard and got me thinking...should be like so.
As developers, ok, as a developer I come along stuff that I call 'HARD'..to me. I dig for info and finally, some developer somewhere, philanthropic enough to share knowledge saves me. (I usually say the grace here..lol :) )
Now, as developers, what if we all share knowledge?? Everything would just go from weird to insane. I mean, all developers would appreciate.
Now, How about the doc below??? It helped me integrate iPay Payment System in a site I was creating some day.
Have a look. Might save somebody!
